This decades-old family-run restaurant knows how to have fun—it even claims to have the most potent margaritas in town. So be warned: Make sure you have a designated driver or rideshare ready before you dive into this drink. The Blue Margarita takes the house recipe (which the restaurant keeps under wraps) and adds blue curaçao, which not only makes it sweeter, but also helps give the drink its color for a great Instagrammable moment.
